The Double Helix Theory of the Magnetic Field The Double Helix Theory of the Magnetic Field Frederick David Tombe Belfast, Northern Ireland, United Kingdom [email protected] 15th February 2006, Philippine Islands Abstract. The historical linkage between optics and electromagnetism can be traced back to a paper published in the year 1856 by Wilhelm Eduard Weber and Rudolf Kohlrausch. By discharging a Leyden Jar (a capacitor), they showed that the ratio of the electromagnetic and electrostatic units of charge is numerically equal to the directly measured speed of light. Weber interpreted this result as meaning that the speed of light is a kind of escape velocity for electricity in motion, such as would enable the associated magnetic force to overcome the electrostatic force. An alternative interpretation was advanced a few years later by James Clerk-Maxwell who connected the result to the elasticity in an all pervading solid medium that serves as the carrier of light waves. As a consequence, he concluded that light waves are electromagnetic undulations. These two perspectives can be reconciled by linking the speed of light to the circumferential speed of the molecular vortices which Maxwell believed to be the constituent particles of the solid luminiferous medium. If we consider these molecular vortices to be tiny electric current circulations, magnetic repulsion can then be explained in terms of centrifugal force. And if these molecular vortices should take the form of an electron and a positron in mutual orbit, we can then also explain magnetic attraction in terms of the more fundamental electrostatic force being channeled through space along double helix chains that constitute magnetic lines of force. Introduction I. The idea that space is dielectric can be inferred from Kepler’s second law of planetary motion. This law, which is essentially the law of conservation of angular momentum, can be used to show that centrifugal force is an outward radial pressure that obeys the inverse cube law in distance. Whereby the inverse square law of gravity indicates a monopole field, the inverse cube law suggests that space contains an electric dipole field as well. The dielectric nature of space might also be inferred from the electric capacitor circuit in the dynamic state. It is unlikely that the surrounding magnetic field will discontinue in the capacitor region while the current is 1 flowing. When a dielectric slab is present in the space between the capacitor plates, we acknowledge the existence of a polarization current. There is no reason to assume that the situation should be any different when the dielectric slab is not present. Since a wave requires a medium of propagation, and since light exhibits wave behavior, it is reasonable to assume that a dielectric luminiferous medium pervades all of space. It then becomes necessary to explain how such a dielectric medium permits the inverse square law of gravity to act in tandem with the inverse cube law of centrifugal force. The Aether (The Electric Fluid) II. ET Whittaker wrote “ - - - All space, according to the young [John] Bernoulli, is permeated by a fluid Aether, containing an immense number of excessively small whirlpools. The elasticity which the Aether appears to possess, and in virtue of which it is able to transmit vibrations, is really due to the presence of these whirlpools; for, owing to centrifugal force, each whirlpool is continually striving to dilate, and so presses against the neighbouring whirlpools - - -”. [1] John Bernoulli was working on the refraction of light. In 1861, James Clerk-Maxwell attempted to explain the magnetic field in terms of a sea of such excessively small whirlpools. In his paper “On Physical Lines of Force” [2], he used such a concept to explain magnetism on the basis that these vortices are aligned solenoidally with their rotation axes tracing out magnetic lines of force. He explained magnetic attraction between unlike poles in terms of a tension existing along the lines of force that connect directly between the two poles. In the case of magnetic repulsion, magnetic field lines spread laterally outwards in the space between two like poles. Maxwell explained the repulsion as being due to centrifugal pressure existing in the equatorial plane of the vortices, hence causing a lateral pressure between the lines of force. Maxwell’s model can be better understood if we replace his molecular vortices with rotating electron- positron dipoles, each of which consists of an electron in a mutual circular orbit with a positron. [3] Such a vortex will then double for both an electric dipole and a magnetic dipole. Aether (electric fluid or free electricity) is the stuff of all matter. Electrons will be considered to be sinks in the aether. Aether is pulled into these electron sinks, hence causing a tension in the surrounding aether which will cause a ‘pull force’ to act on other particles. A positron is an aether source from which a pressurized fountain of aether emerges. The aether is dynamical, compressible, stretchable, and it gives fluids their characteristics. There will be a vector A equal to ρv, where ρ is the density of the aether, and v is the velocity of an element of the aether relative to the rest of the aether. Modern textbooks refer to A as the ‘magnetic vector potential’, but it more accurately constitutes a 2 momentum per unit volume. The vector A can represent both gravity and electric current. Free electric current is however commonly denoted by the symbol J, whereas A tends to be reserved for the circulating current in a molecular vortex. Maxwell identified the quantity A with Faraday’s electrotonic state. If we keep the aether density constant in time, we can expand the force expression F = dA/dt to obtain, F = ∂A/∂t − v×B + (A.v) (1) where B =×A. See Appendix A. Eq. (1) is recognizable as the ‘Lorentz force’, but the terms in the Lorentz force appeared in Eqs. (5) and (77) of Maxwell’s 1861 paper, which was written when Lorentz was only eight years old. It would be more accurately called the ‘Maxwell Force’. Taking the curl of Eq. (1) we obtain, ×F = ∂B/∂t + (v.)B = dB/dt (2) which is a total time derivative expansion of Eq. (54) in Maxwell’s 1861 paper. See Appendix B. Oliver Heaviside always referred to Maxwell’s Eq. (54) as Faraday’s law, even though it is not strictly speaking Faraday’s law as such. Maxwell’s Eq. (54) is similar to Faraday’s law, but it doesn’t account for convectively induced electromotive force. The first term on the right hand side of Eq. (1) represents the force due to tension or pressure in the aether. Around a sink or a source, this tension or pressure can be split into a radial (irrotational) component and a transverse (angular) component. The irrotational radial component can be represented in the form Ψ, where Ψ is a scalar potential function. The second and third terms on the right hand side of Eq. (1) can each be either the Coriolis force or the centrifugal force. In a sea of molecular vortices, these convective forces can manifest themselves in a number of fashions. The transverse Coriolis force arises in cyclones and in non-circular planetary orbits in conjunction with the conservation of angular momentum. We also witness a Coriolis force in a rigid rotating body when it is forced to precess. This induced Coriolis force can prevent a gyroscope from toppling under gravity. Centrifugal force acting on the individual elements of a rigid body that is rotating on an asymmetrical axis causes the rotation to realign. This can completely reverse the direction of rotation, as is witnessed in the case of a rattleback. Centrifugal pressure in the electron-positron sea keeps the planets from falling down, while differential centrifugal pressure between air molecules, above and below a wing, keeps aeroplanes in flight. The convective forces are also responsible for both the magnetic force that is induced on a current carrying wire in a magnetic field, 3 and the induced electromotive force in a wire that is moving at right angles through a magnetic field. The Double Helix Alignment III. Lenz’s law can be understood on the basis that any stretching of the aether will have a tendency to tighten the electron sinks and to widen the positron sources. This will result in the generation of aether pressure that will oppose the tension that has created it. Tension in the aether may be caused by 1) stretching the dipoles linearly, hence causing them to precess, and 2) stretching the dipoles torsionally so as to increase their vorticity. These actions both lead to the centrifugal and Coriolis pressures that underlie magnetization and gyroscopy. When a dipole is caused to precess out of its solenoidal alignment, it will be forced back into line again by induced aether pressure, and during this process, the circumferential motion of the electrons and the positrons will be deflected at right angles into the axial direction. This fundamental axial Coriolis force underlies Ampère’s Circuital Law. In the solenoidal equilibrium state, the electron-positron dipoles, all rotating in the same direction, will be aligned in a double helix fashion, with their rotation axes tracing out magnetic lines of force. An electrostatic tension will exist along these lines of force due to the fact that the electrons and the positrons will be alternately stacked. See Fig. 1, Fig. 1. A single magnetic tube of force. The electrons are shown in red and the positrons are shown in black. The double helix is rotating about its axis with a circumferential speed equal to the speed of light, and the rotation axis represents the magnetic field vector H.

  • On the First Electromagnetic Measurement of the Velocity of Light by Wilhelm Weber and Rudolf Kohlrausch
    Andre Koch Torres Assis On the First Electromagnetic Measurement of the Velocity of Light by Wilhelm Weber and Rudolf Kohlrausch Abstract The electrostatic, electrodynamic and electromagnetic systems of units utilized during last century by Ampère, Gauss, Weber, Maxwell and all the others are analyzed. It is shown how the constant c was introduced in physics by Weber's force of 1846. It is shown that it has the unit of velocity and is the ratio of the electromagnetic and electrostatic units of charge. Weber and Kohlrausch's experiment of 1855 to determine c is quoted, emphasizing that they were the first to measure this quantity and obtained the same value as that of light velocity in vacuum. It is shown how Kirchhoff in 1857 and Weber (1857-64) independently of one another obtained the fact that an electromagnetic signal propagates at light velocity along a thin wire of negligible resistivity. They obtained the telegraphy equation utilizing Weber’s action at a distance force. This was accomplished before the development of Maxwell’s electromagnetic theory of light and before Heaviside’s work. 1. Introduction In this work the introduction of the constant c in electromagnetism by Wilhelm Weber in 1846 is analyzed. It is the ratio of electromagnetic and electrostatic units of charge, one of the most fundamental constants of nature. The meaning of this constant is discussed, the first measurement performed by Weber and Kohlrausch in 1855, and the derivation of the telegraphy equation by Kirchhoff and Weber in 1857. Initially the basic systems of units utilized during last century for describing electromagnetic quantities is presented, along with a short review of Weber’s electrodynamics.

  • History (From Wikipedia)
    History (from Wikipedia) November 13, 2019 There’s a reason math things are named after physicists: 1. Friedrich Wilhelm Bessel was a German astronomer, mathematician, physicist and geodesist. He was the first astronomer who determined reliable values for the distance from the sun to another star by the method of parallax. A special type of mathematical functions were named Bessel functions after Bessel’s death, though they had originally been discovered by Daniel Bernoulli and then generalised by Bessel. 2. Pierre-Simon, marquis de Laplace: was a French scholar whose work was important to the devel- opment of engineering, mathematics, statistics, physics, astronomy, and philosophy. He summarized and extended the work of his predecessors in his five-volume Mécanique Céleste (Celestial Mechanics) (1799–1825). This work translated the geometric study of classical mechanics to one based on calculus, opening up a broader range of problems. In statistics, the Bayesian interpretation of probability was developed mainly by Laplace. 3. Adrien-Marie Legendre: Whoops, he’s a mathemetician. But much of his work was completed by Gauss. Legendre is known for the Legendre transformation, which is used to go from the Lagrangian to the Hamiltonian formulation of classical mechanics. In thermodynamics it is also used to obtain the enthalpy and the Helmholz and Gibbs (free) energies from the internal energy. He is also the namesake of the Legendre polynomials, solutions to Legendre’s differential equation, which occur frequently in physics and engineering applications, e.g. electrostatics. 4. Carl Gottfried Neumann, while in Königsberg, studied physics with his father, and later as a working mathematician, dealt almost exclusively with problems arising from physics.

    The Full Significance of the Speed of Light Frederick David Tombe, Northern Ireland, United Kingdom, [email protected] 15th June 2019 Abstract. In the year 1855, German physicists Wilhelm Eduard Weber and Rudolf Kohlrausch performed a landmark experiment of profound significance. By discharging a Leyden jar (a capacitor), they linked the speed of light to the ratio between electrostatic and electrodynamic units of charge. This experiment was electromagnetism’s Rosetta Stone because the result can be used to, (i) identify the speed of light as the speed of circulation of electric current, (ii) identify the speed of light as the speed of electromagnetic waves through a dielectric solid that pervades all of space, while noting that inertial centrifugal force and dipole fields share in common an inverse cube law in distance. The result can also be used to, (iii) identify magnetic repulsion as a centrifugal force, and hence to establish the double helix pattern that characterizes magnetic lines of force. Weber’s Interpretation I. Weber and Kohlrausch’s 1855 experiment involved discharging a Leyden jar (a capacitor) that had been storing a known amount of charge in electrostatic units, and then seeing how long it took for a unit of electric current, as measured in electrodynamic units, to produce the same deflection in a galvanometer [1]. From these readings they discovered that the ratio of the two systems of units was equal to c√2 where c is the directly measured speed of light, although it’s not clear that they immediately noticed the numerical value of c explicitly. Had they however used electromagnetic units instead of electrodynamic units for the electric current, the result would have stood out as c exactly.

  • Investigation of the Influence of a Field-Free Electrostatic Potential on the Electron Mass with Barkhausen-Kurz Oscillation
    Investigation of the Influence of a field-free electrostatic Potential on the Electron Mass with Barkhausen-Kurz Oscillation M. Weikert and M. Tajmar1 Institute of Aerospace Engineering, Technische Universität Dresden, 01062 Dresden, Germany Abstract According to Weber’s electrodynamics, Assis showed analytically, that a field-free electrostatic potential delivered by a spherical shell causes a force upon a moving electrical charge in the center of that shell. This force can be interpreted as a result of the change in inertial mass of the charge. In order to prove this theory, Mikhailov published two type of experimental setups: One using vacuum cathode tube and another using glow-discharge- lamps to generate oscillating and accelerating electrons. Whereas the glow-discharge experiment was already evaluated by several groups, here we are focusing on replicating the vacuum tube configuration. Under right circumstances, electrons inside a vacuum tube start to oscillate around a grid electrode, which is called Barkhausen-Kurz oscillations. However, we found that Mikhailov’s setup does not produce these kind of oscillations and therefore the theory that he applied in the interpretation of his measurements is not correct. We succeeded in generating Barkhausen-Kurz oscillations with a different vacuum tube and found no frequency shifts below an order of magnitude of Assis’s prediction by operating the tube inside a charged spherical shell that would indicate a change in the electron’s mass. However, since both the mass as well as the geometry factor of the electron cloud contribute to the oscillator frequency, we believe that this setup is not suitable to investigate Weber-type electrodynamic effects.

  • The 1856 Weber-Kohlrausch Experiment (The Speed of Light)
    The 1856 Weber-Kohlrausch Experiment (The Speed of Light) Frederick David Tombe, Northern Ireland, United Kingdom, [email protected] 18th October 2015 Abstract. Nineteenth century physicists Wilhelm Eduard Weber, Gustav Kirchhoff, and James Clerk-Maxwell are all credited with connecting electricity to the speed of light. Weber’s breakthrough in 1856, in conjunction with Rudolf Kohlrausch, revealed the speed of light in the context of a ratio as between two different units of electric charge. In 1857 Kirchhoff connected this ratio to the speed of an electric signal travelling along a wire. Later, in 1862, Maxwell connected this ratio to the elasticity in the all-pervading luminiferous medium that serves as the carrier of light waves. This paper sets out to establish the fundamental cause of the speed of light. Introduction I. The 1856 Weber-Kohlrausch experiment established a ratio between two different units of electric charge. The experiment involved discharging a Leyden jar (a capacitor) that had been storing a known amount of charge in electrostatic units, and then seeing how long it took for a unit of electric current, as measured in electrodynamic units, to produce the same deflection in a galvanometer. This resulted in a ratio C, known as Weber’s constant, and we know today that it is equal to c√2 where c is the directly measured speed of light. Weber interpreted this ratio in connection with the convectively induced force that he had identified and formulated in 1846 as between two charged particles in relative motion. He believed C to be the speed that would produce an exact counterbalancing force to the electrostatic force.

  • Carl Friedrich Gauss English Version
    CARL FRIEDRICH G AUSS (April 30, 1777 – February 23, 1855) by HEINZ KLAUS STRICK, Germany Even during his lifetime, the Braunschweig (Brunswick) native CARL FRIEDRICH GAUSS was called princeps mathematicorum, the prince of mathematics. The number of his important mathematical discoveries is truly astounding. His unusual talent was recognized when he was still in elementary school. It is told that the nine-year-old GAUSS completed almost instantly what should have been a lengthy computational exercise. The teacher, one Herr Bu¨ttner, had presented to the class the addition exercise 1 + 2 + 3 + · · · + 100. GAUSS’s trick in arriving at the sum 5050 was this: Working from outside to inside, he calculated the sums of the biggest and smallest numbers, 1 + 100, 2 + 99, 3 + 98, . , 50 + 51, which gives fifty times 101. Herr BÜTTNER realized that there was not much he could offer the boy, and so he gave him a textbook on arithmetic, which GAUSS worked through on his own. Together with his assistant, MARTIN BARTELS (1769-1836), BüTTNER convinced the boy’s parents, for whom such abilities were outside their ken (the father worked as a bricklayer and butcher; the mother was practically illiterate), that their son absolutely had to be placed in a more advanced school. From age 11, GAUSS attended the Catherineum high school, and at 14, he was presented to Duke CARL WILHELM FERDINAND VON BRAUNSCHWEIG, who granted him a stipend that made it possible for him to take up studies at the Collegium Carolinum (today the University of Braunschweig). So beginning in 1795, GAUSS studied mathematics, physics, and classical philology at the University of Go¨ttingen, which boasted a more extensive library.
